7-mode/HA pair/V-Series : Aggregates : Understanding aggregates : What mirrored aggregates are
What mirrored aggregates are
A mirrored aggregate is a single WAFL storage file system with two physically separated and synchronously up-to-date copies on disks or array LUNs. These copies are called plexes.
Data ONTAP
typically names the first plex
plex0
and the second plex
plex1
.
Each plex is a physical copy of the same WAFL file system, and consists of one or more RAID groups. As
SyncMirror
duplicates complete WAFL file systems, you cannot use the
SyncMirror
feature with a
FlexVol
volume—only aggregates (including all contained
FlexVol
volumes) are supported.
